Key Takeaways:

The NTSB concluded that improper maintenance during a brake system modification caused an American Airlines Boeing 737-800 to overrun a runway at Dallas/Fort Worth International Airport.
The specific errors involved mistakenly swapped flexible hydraulic hoses on the right main landing gear and cross-connected anti-skid wiring harnesses on the left, leading to a loss of braking effectiveness.
Though the aircraft overran the runway, all 104 passengers and crew exited without injury.
Following the incident, both American Airlines and Boeing implemented new procedures, labeling requirements, and functional checks to prevent similar maintenance errors in the future.
